Maryland, Chicago, Ill. 60619 Filed Aug. 27, 1964, Ser. No. 392,447 1 Claim. (Cl. 131--246) This invention relates .broadly to smokers accessories and, more specifically, to appliances which are designed to clear away accumulated obstructions of any kind and to loosen and remove any deposits in the bowl to a tobacco pipe.

The principal object of the present invention is to provide novel and improved accessories of the Iaforementioned comprising parts of special construction and operation.

A second object of the invention is to provide a smokers article .of the type aforementioned which is composed of two parts which will, when assembled, -provide a tool for reaming out the layer -of hard ash that forms on the inside of a smoking pipe bowl.

A third object of the invention is to provide a reamer having novel helical tooth cutters on the convex outer surface thereof, the latter of which is adapted to scrap the cake from the inside of a pipe bowl when rotated therein.

Further objects of the invention of the class described are to provide a combination pipe bowl and Ipipe stem cleaner set that is extremely inexpensive, easy to use, versatile, pleasing in appearance, simple to manufacture, and a set that is adaptable for use in many different sizes, types and styles of pipe bowls.

Other objects will be in part apparent and in part pointed out specifically hereinafter in connection with the description of the drawing that follows, in which:

Referring now to the drawing for a detailed description of the invention, and in particular to FIGURES 1-6 thereof, it will be seen that the pipe cleaner, which has been identified broadly by numeral 15, consists of a body, or wooden handle 16, or other suitable material can'be used, and a metal -reamer 17 assembled together. The handle 16 has a rounded free end portion 18 at one end, and at its opposite end is provided with a disc portion 19 of maximum diameter substantially the same as the transverse diameter of the handle, a disc or stepportion 20 of smaller diameter than said disc portion 19, and a tenon 21 carried by and spaced axially fr-om the body 16 Iby said disc portion 19 and step portion or disc 20, said tenon being a truncated "conical head member integrally formed with said discs 19, 20 and body 16 forming a `one piece handle 15.

The reamer 22 is removably connected with the truncated conical head 21, of handle 15, by a close friction tight fit. The reamer 22 has the general contour of an ellipsoid, the end portions 25 and 26 of which are truncated, the-major rear end of the -body being indicated by numeral 25 and the minor end by the numeral 26. The reamer 22 is of hollow form, having a tapered or truncated conical socket 24 therein, the outlet of said socket 24 being adjacent the rear end 25 thereof. The base of the socket has a short cylindrical chamber 27 therein. An axial channel 28 extends from the fiat end surface 29 of the reamer and communicates with said chamber 27 to provide an air passage therebetween and air in the chamber at atmospheric pressure. The smal-L er end of the conical head 21 extends into the chamber 27 las `surface wear develops :be-tween head 21 and socket 24 during use thereof. The reamer 22 is provided with coarse helical tooth cutters 30 formed on the curved longitudinal surface by the helical grooves 32 arranged therein.

The pipe 35 shown in FIGURE l consists of a pipe bowl 36, shank 37, the shank having a bore 38 cornmunicating with the bowl. The stern 39 may be made of hard rubber, or other material; the bite 40 is flattened in the usual manner. The stem 39 has a cylindrical tenon 41 which has a close sliding fit with bore 38 of shank 37. A ymetal tube 42 is -assembled in the longitudina'l bore 43 in the stem 39, the outer free end of the tube 42 extending into bore 38. The stem 39 is removably fitted into the bore 38 of shank 37, the stem being easily removed to be cleaned and allowing easy access to clean bore 38. In general the maximum outside diameter of the reamer is somewhat less than the diameter of the opening 45 of the pipe bowl 36; this becomes important to the reaming operation of the baked ash 44 which forms in the 'bowl 36. The cutters 30 formed by a `series of alternating grooves 32 define sharp edges which scrape the cake 44 from the inside of the pipe bowl when the handle 15 is -grasped by the user, the reamer inserted into the bowl and rotated with a reaming action against the internal surface of the bowl. The reamer is so formed that it can be inserted substantially all the way into the bottom of the bowl. Various size reamers may be placed upon the conical head 21 of handle 15; the reamer 22 can be 4pried off by inserting a tool, or coin, between the end 25 of the reamer and disc 19 of the handle 15.

Referring to FIGURES 7-10, a liquid absorbing tool is shown, which has been identified broadly by numeral 50, which consists of a handle 51 with rounded free rear end 52, the handle 51 having a truncated conical socket 53 in the opposite end thereof. A liquid absorbing head member 54, formed of rubber or the like, has a configuration similar 'to a segment lof paraboloid of revolution; or an elilipsoid, with small flat end 55, and a fiat rear end 56 with 4substantially truncated conical head, or tenon 58. The said Vtenon 58 being of such a sizeas to have a c-lose sliding t with socket 53 when assembled therewith. The tenon 58 is provided with longitudinal slots or grooves S9 to receive longitudinal key members 60 formed on side walls of socket 53. The rubber head 54 can be inserted vinto the bowl land rotated by the user grasping handle 50 and rotating it with a wiping action against the interior pipe bowl surfaces.

Referring to FIGURE 11, a stem-bore cleaner 70 is shown having cylindrical wood head portion 71 and a long working portion 72 formed of a wire containing absorbent material 73 exposed throughout its length, made in a way which is known in the art.

Referring to FIGURE 12, a pipe shank `bore cleaner 77 is shown -with head portion 75 and working ,portion 76, said `portion 76 being relatively short, made of wire covered with absorbent material 78. By removing stem 39 from bore 38 of shank 37, it is easy to operate the bore cleaner 77 within bore 38.

Having thus described the several useful and novel features of the -pipe cleaner set of tools of the present invention, it will be seenthat the many worthwhile objects for which it was designed have been achieved. While only a few specific embodiments of the invention h-ave been illustrated in the accompanying drawings, we realize that certain changes land modifications therein may well occur to those skilled in the art within the `broad teaching thereof; hence, it is my intention that the scope of protection afforded hereby shall be limited only insoar as said limitations are expressly set forth in the appended claim.
